The Lowdown
Alright, Rusty here. Let’s break down the next stretch for Costeño Beach.
First off, the opening days are a bit of a bummer. A small, short-period NE swell, nothing over 5 ft, with a cross-onshore wind messing things up. The wave energy is weak, only around 234 (combined energy) early on, and the water temp is 84°F, which is pretty normal for the season. You’re looking at choppy, lumpy conditions, not much to write home about.
There’s a lull through the end of August and into early September. You get some glassy windows, like the afternoon of the 31st (Monday) and the 1st of September (Tuesday), but the swell is tiny, only 3 to 4 ft, and the period is short. The energy is real low, like 93 to 165 (combined energy). You can paddle out, but it’s pretty ordinary.
The big news is the second week. The afternoon of the 8th of September (Tuesday) is the standout. The swell bumps up to 7 ft from the NE, period around 8 seconds, and the energy hits 579 (combined energy). With glassy, calm conditions, that’s going to be clean and fun. That’s the best call of the whole forecast.
The 11th of September (Friday) afternoon is another cracker. Swell is 7 ft from the NE, energy is strong at 634 (combined energy), and it’s glassy again. The 12th of September (Saturday) afternoon also looks good, with 6 ft and glassy winds, energy at 505 (combined energy). A solid run of quality surf.
The short period keeps the waves from being too perfect at a beach break, but it also means you’ll get plenty of them. When the wind drops off, Costeño turns on. The first week is a dud. The second week is where it’s at. Get on it.
Rusty.

The above surf forecast table for Costeño Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Costeño Beach can be found by selecting the local surf guide option on the grey menu. Our Costeño Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Costeño Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Costeño Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
